标准简介：This part of IEC 60947 applies to flow rate switches that sense the rate of flow of a gas, a liquid or a granular solid. These switches change their output state if a pre-set value for the speed of flow is exceeded.
These flow rate switches are self-contained, have semiconductor switching element(s) and
are intended to be connected to circuits, the rated voltage of which does not exceed 250 V
50 Hz/60 Hz a.c. or 300 V d.c.
This standard does not specify the additional measures that are necessary for flow rate
switches used in conjunction with explosive sensing materials and/or in an explosive location.
This standard is not intended to cover devices with analogue outputs.
